real and imaginary parts of an expression

Physicslad78

can anyone tell me how to get the real and imaginary parts of the following function :

(x+ i y)* Log( a+i b) where x, y a and b are all real numbers and i =sqrt (-1).

Thanks very much

Recall that Log(z) = ln|z| + iArg(z). When you write it like that, it is easy to separate the expression into real and imaginary parts.
